Definitions
- the present invention relates, in general, to a tamping machine for tamping ballast underneath ties of a track.
- U.S. Pat. No. 4,632,037 discloses a tamping machine having a machine frame extending in a longitudinal direction and supported on the track by two undercarriages for mobility in an operating direction.
- a sub-frame is arranged between the undercarriages and supported for mobility on the track by a further undercarriage having a unit motive drive.
- the sub-frame is connected to the machine frame by means of a frame support for displacement relative thereto in the longitudinal direction.
- a vertically adjustable tamping unit and track lifting unit are arranged on the sub-frame between the further undercarriage and the frame support.
- a tamping machine of this type there is no need to stop a major part of the overall mass of the tamping machine, each time a tie is to be tamped, and then to accelerate it again, as only the sub-frame, carrying the working units, is subjected to this stop-and-go procedure.
- the displacement of the sub-frame is effected, on the one hand, by a motive drive integrated in the undercarriage of the sub-frame, and, on the other hand, by means of a hydraulic cylinder connecting the machine frame and sub-frame to one another.
- a tamping machine for tamping ballast underneath ties of a track
- a machine frame extending in a longitudinal direction and supported on the track by two undercarriages for mobility in an operating direction; and a sub-frame arranged between the said undercarriages and supported for mobility on the track by a further undercarriage comprising a unit motive drive, the sub-frame being connected to the machine frame by means of a frame support for displacement relative thereto in the longitudinal direction.
- a vertically adjustable tamping unit and a track lifting unit are arranged on the sub-frame between the further undercarriage and the frame support.
- An acceleration drive is provided for assisting the unit motive drive in displacing the sub-frame in the longitudinal direction, the acceleration drive being rigidly connected to the machine frame by means of a drive fastening and comprising a piston end including a bracing plunger provided for temporary application to the sub-frame, wherein a maximum stroke m of the acceleration drive is shorter than a maximum displacement path a of the sub-frame relative to the machine frame.
- the latter has the effect of an impulse generator, used for providing optimum assistance of the acceleration and support of the starting motion of the sub-frame.
- an impulse generator used for providing optimum assistance of the acceleration and support of the starting motion of the sub-frame.
- the acceleration drive provided for assisting the unit motive drive in displacing the sub-frame in the longitudinal direction is rigidly connected to the sub-frame by means of a drive fastening and comprises a piston end including a bracing plunger provided for temporary application to the machine frame, wherein a maximum stroke m of the acceleration drive is shorter than a maximum displacement path a of the sub-frame relative to the machine frame.
- FIG. 1 is a schematic side elevational view of one embodiment of a tamping machine according to the present invention
- FIG. 2 is a detailed top view, on an enlarged scale, of a part of the tamping machine, showing in detail an arrangement of two secondary acceleration drives;
- FIG. 3 is a schematic fragmentary top view of another embodiment of a tamping machine according to the present invention.
- a tamping machine 1 which includes a machine frame 2 extending in a longitudinal direction and mobile by means of on-track undercarriages 3 , arranged at each end respectively, on a track 6 composed of ties 4 and rails 5 .
- the machine 1 is equipped with a motor 7 and a motive drive 8 .
- a control device 10 is located in a work cabin 9 .
- a sub-frame 11 is arranged between the two on-track undercarriages 3 of the machine frame 2 .
- the latter is equipped with a further undercarriage 14 .
- two frame beams 16 are provided which are arranged in opposite relationship to one another transversely of the longitudinal direction of the machine and are supported for displacement in the longitudinal direction by means of frame supports 17 mounted to the machine frame 2 .
- the undercarriage 14 of the sub-frame 11 is equipped with its own primary unit motive drive 18 .
- a tamping unit 19 designed for the simultaneous tamping of three ties 4 is provided on the sub-frame 11 .
- a track lifting unit 20 precedes the tamping unit 19 in the operating direction 12 , and both units 19 and 20 are connected for vertical adjustment to the sub-frame 11 .
- a secondary acceleration drive 21 is provided between the rear end 13 of the sub-frame 11 and the machine frame 2 .
- the acceleration drive 21 is designed as a hydraulic cylinder and is connected by means of a drive fastening 22 rigidly and exclusively to the machine frame 2 .
- the hydraulic acceleration drive 21 has a free piston end 23 at which a bracing plunger 24 is provided, intended for temporary application to the sub-frame 11 .
- a maximum stroke “m” of the acceleration drive 21 is preferably about 800 mm, which is shorter than a maximum displacement path “a” of the machine frame 2 relative to the sub-frame 11 .
- a second acceleration drive 25 with a bracing plunger 26 is provided in order to further assist in the initial acceleration of the sub-frame 11 , the acceleration drive 25 being connected to the machine frame 2 by means of a further drive fastening 27 .
- a maximum stroke of said second acceleration drive 25 measures merely 120 mm.
- a spring buffer 28 is connected to the machine frame 2 between the two acceleration drives 21 and 25 .
- the motion of the sub-frame 11 is composed of a quick forward acceleration and a subsequent local stoppage for carrying out a tamping operation under the ties 4 .
- the forward acceleration takes place starting from a rearward end position (shown in FIGS. 1 and 2 in solid lines) and progressing to a forward end position (shown in dash-dotted lines).
- the two acceleration drives 21 and 25 are actuated.
- the bracing plunger 24 situated in the forward end position is gradually applied to the sub-frame 11 with the forward movement of the machine frame 2 .
- an extended piston rod 29 connected to the bracing plunger 24 and being in a pressureless floating position, is thereby moved back into the initial position.
- the second bracing plunger 26 is also moved back into its initial position.
- FIG. 3 there is shown another embodiment of a tamping machine according to the present invention. Parts corresponding with those in FIG. 1 are denoted by identical reference numerals and not explained again. The description below will center on the differences between the embodiments.
- the acceleration drives 21 , 25 are fastened to the sub-frame 11 , and the bracing plungers 24 , in turn, bear on the machine frame 2 .
